Casio IT-2000 installation manual Setup of Master I/O Box

2.3.2Setup of Master I/O Box

Note that the DIP switch settings of the Master I/O Box differ depending on whether the

system configuration is consisted of only single Master I/O Box or of multiple Master I/O Boxes that are￿followed by Satellite I/O Boxes.

Make sure that the POWER switch of the I/O Box is set to OFF. Set the DIP switch at the rear of the unit as follows:

	1	2	3	4	5	6	7	8	9	10
￿	ON	OFF	OFF	OFF	ON	OFF	OFF	OFF	ON	ON

Setup for the SCSI ID (DIP switches nos. 6, 7, and 8)

This SCSI ID must be different from that of other I/O Boxes or the PC.

Since generally the SCSI ID of the PC is set to 7, set the SCSI ID of the I/O Box to a number between 0 and 6.

	SCSI-ID	6	7	8
	ID0	OFF	OFF	OFF
	ID1	ON	OFF	OFF
	ID2	OFF	ON	OFF
	ID3	ON	ON	OFF
	ID4	OFF	OFF	ON
	ID5	ON	OFF	ON
	ID6	OFF	ON	ON
￿	ID7	ON	ON	ON

Setup termination for SCSI interface (no. 9)

Set DIP switch no.9 of the I/O Box, which is the farthest from the PC, to ON.

This setting is the same if only one I/O Box is connected.

SCSI termination setup	9
Termination	ON
Non-termination	OFF

Power setup for termination of SCSI interface (no.10)

If the SCSI board in the PC cannot supply power to the SCSI interface, set DIP switch no.10 of the I/O Box, which is the nearest to the PC, to ON. However, DIP switch no. 10 is usually set to OFF, since a general SCSI board can supply power to the SCSI interface.
